Abstract: Disclosed is a fuel cell with improved thermal distribution in a stack including two more unit cells stacked therein. The fuel cell includes a stack including the two more unit cells and separators each having manifolds formed through four sides thereof, a first chamber having an internal space so as to receive air and fuel from the outside and to transfer the air and fuel to a second chamber and so as to receive the air and fuel discharged from the stack and to discharge the air and fuel to the outside, a second chamber having an internal space so as to receive the air and fuel from the first chamber and to transfer the air and fuel to the stack, and a connecting part connecting the first chamber to the second chamber so as to allow the air and fuel to flow to the second chamber from the first chamber.

Abstract: Disclosed are a separator for fuel cells capable of minimizing the volume of a system and the use of sealants, and a stack for fuel cells, more particularly, a stack for solid oxide fuel cells, including the same. Specifically, by adding a metal sheet having a specific shape, position and size to the separator, the stress applied to the sealant can be uniformized, and thus the oxidizing agent and fuel can be separated and electrically isolated using only a piece of sealant. Therefore, the stack for fuel cells is characterized in that there is no variation in temperature, reactant concentration, power, or the like between respective unit cells, so delamination and microcracks do not occur, the volume is minimized, and the power density per unit volume is very high.

Abstract: This application relates to a separator for a fuel cell and a fuel cell stack with improved durability, which contains the same, particularly to a solid oxide fuel cell stack. Specifically, this application allows an oxidizer and a fuel to flow in a counter-flow manner and a cross-flow manner in the fuel cell stack by forming an outlet manifold and an inlet manifold to have a specific shape, location and size in the separator. As a result, interlayer peeling, microcracking, etc. are prevented because no variation in temperature, reactant concentration, power, etc. occurs between each unit cell and the power density per unit volume is significantly improved because the volume is minimized.

Abstract: Disclosed herein are a fuel cell manifold and a fuel cell stack including the same. The manifold may include a cover plate, an air guide plate configured to guide a flow of air in the manifold, a fuel guide plate configured to guide a flow of fuel in the manifold, and an auxiliary plate providing a passage for inflow of air and outflow of fuel.
